Pong game end screen buttons not working

Hi, for some reason my end game screen at the very end, when I press the respected keys doesn’t go to that stage. When I do it on the menu screen however it works. I have no idea why.

//all major variables
int x,y,w,h,speedX,speedY;//circle variables
int paddleX, paddleY,paddlew,paddleH,paddleS,paddleX2,paddleY2,paddlew2,paddleH2,paddleS2;//left and right paddles variables
boolean up,down;//up down for right paddle
boolean positive, negative;//up down for left paddle
boolean a_pressed=false;//pauses game
boolean q_pressed=false;//unpauses game
int scoreL=0;
int scoreR=0;
int stage=1;
void setup() {
  size(600,600);
  //circle variables values
  x=width/2;
  y=height/2;

  speedY=3;
  //paddle 1 values
  paddleX=570;
  paddleY=height/2;
  paddlew=30;
  paddleH=100;
  paddleS=5;
  //paddle 2 values
  paddleX2=10;
  paddleY2=height/2;
  paddlew2=30;
  paddleH2=100;
  paddleS2=5;
  //switching screens
  print("Stage 1=Menu","Stage 2=Game","Stage 3=Instructions","Stage 4=End game");
}
  void draw() {

You must activate the loop after a game has ended
If the loop is disabled, processing cannot detect pressed buttons. If you remove noLoop, processing will also recognize keyActions while delay


//preventing it leaving screen
if(x>width-w/2){
  speedX=-speedX;
  noLoop();// left paddle ,stops game if ball hits screen and player misses to hit it(end game)
  delay(4000);
  loop();
  stage=4;
}else if(x<0+w/2) {
  speedX=-speedX;
  noLoop();// right paddle ,stops game if ball hits screen and player misses to hit it(end game)
  delay(4000);
  loop();
  stage=4;
}

Ideally, do not use delay() at all – it causes your screen to freeze. Instead, a simple timer that allows your sketch to continue.

// something happened -- lets go into delay mode 
mydelay = frameCount + 240; // 4 seconds @ 60fps

void draw() {
  if(frameCount > mydelay) {
    // all the things you do when not delaying
  }
}
